To be fair I've not had much of a problem trying to get served anywhere.
Even Northwich sorting office isn't bad.
I once had the misfortune to work there, not be it known, since it became a 'Spoons, but way back in the days when it was still a Post Office. I usually worked elsewhere but got sent there for a few days to help them out because they were short staffed. You could see the turnstiles at Witton Albion through a gap between the buildings across the street.
I should mention at this juncture that there was also a lad from Liverpool there who had also been sent 'to help out' but it became very evident before we had even started that it would be a miracle if he managed to get through the day without offending the locals. It was a Monday morning and very busy for the first half an hour or so, until eventually, the office was completely empty, whereupon, a Clergyman (wearing his dog collar and black cassock) entered stage left and made a bee-line for the Scouser who was closest in his line of sight. He then placed an envelope on the scales and...
Clergyman: "Can I send this letter first class and will it arrive tomorrow?"
Scouser: (Places hands together and closes eyes as in prayer) "Let us all pray together that our gracious God speeds well the passage of this holy message and for Cherubims and Seraphims to rejoice upon deliverance to... errrmmm... Bootle "
Clergyman: "I beg your pardon"
Scouser: "...and some fell on stoney ground"
10 minutes later, another customer, an OAP who wants to buy a Dog Licence.
OAP: "I would like to buy a licence for my dog please"
Scouser: "Is it a coloured or a black and white dog?"
A few moments later...
Scouser: "Name please"
OAP: "Rex"
Scouser: "Not the dog's name, your name"
OAP: "That IS my name!"
No Customer Charters or Mission and Vision Statements in the 1970s. Ahhh... the bad old good old days.
